The ignition system uses individual ignition coil/module assemblies for each cylinder. The engine control module (ECM) controls the individual coils by transmitting timing pulses on the ignition control (IC) circuit of each ignition coil/module to enable a spark event. The ECM monitors each IC circuit for improper voltage levels. Each ignition coil/module has the following circuits:
• | Ignition voltage |
• | Ground |
• | IC |
• | Low reference |
• | The engine is running. |
• | DTCs P0351-P0356 run continuously when the above condition is met. |
The ECM detects an open, short to ground, or a short to voltage on the IC circuit or the ignition coil/module for less than 1 second.
DTCs P0351-P0354 are Type B DTCs.
DTCs P0351-P0354 are Type B DTCs.
Powertrain Diagnostic Trouble Code (DTC) Type Definitions
Control Module References for scan tool information
⇒ | If a fault is found, repair the circuit as needed. |
⇒ | If the DTC or the misfire transfers with the suspect ignition/coil module, replace as needed. |
⇒ | If the DTC or the misfire does not transfer with the suspect ignition/coil module, replace the ECM. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
